| Abstract: | The dynamic plastic buckling of cylindrical shells subjected to nonuniform external irnpulsiveloads is analysed with the dynarnic buckling criterion propcoed by Wang and Ru. The formulae of per-ferred mode numbers and critical loads of buckling are given and proved by the experimental resultsgiven by Lindberg and Florence. We also conclude that the energy criterion proposed by Wang and Ruis a suitable method for dealing with the buckling problems discussed by this paper. |
